To all whom it may concern:

Be it known that I, JAMES M. CALLAHAN, a citizen. of the United States, residing at Washington, in the District of Columbia., have inventedciJ new and useful Adjustable Arch-Support for Shoes; und I do hereby declare the following to be a full, clear, und exact description of the invention, such as will enable others skilled in the art to which it apperteins to make and use the same.

l This invention relates to a new and useful adjustable arch support to `be 'worn upon the interior of the shoe adjacent the arch, :md the ob'ect of the invention is to provide u. device o this kind for strengthening, reinforcing, and restoring fallen or broken or wrenched arches to their normal condition, whereby a person can walk without pain or inconvenience.

A further object of the invention is to provide a support, to reinforce and support the 'longitudinal and tranverse arch of the foot.

A further object of the invention is to provide an insert pad between a plate and an insole, l(rnd which pad may be any suitable shape, and provided with an increased thickness at its forward end, to support the trans verse arch, while the increased thickness of the pad near its central orton reinforces und supports the longitudinal arch.

A further object of the invention is to provide n supporting plate constructed of two distinclJ thicknesses, in other words, a. plurality of thicknesses.

A further object of the invention is toprovide an insole, thc heel ortion of which-is constructed of two thic` esses of leather, which may be secured together by any suitV :rblc menus, preferably adhesive material or stitches, to reinforce the heel of the insole relative to the metallic srch supporting plate.

A further object of the invention 'is to provide the entre thickness of leather for the heel. of the insole, as having n forwardly curved portion. to engage the correspondingly curved odge of the metallic urrh reiny forcing plete, thereby reinforcing the insole with relation tosuil pluto, :is well :is provid-l ing abutment menus to prevent the insole frorr creeping forwardly, und also reinforcing the insole relative to where it bends ad- ]eeent said plate, as well as still'ening the heel of the insole.

A further' object of the double thicknesses 56 of heel for the insole is to provide a more convenient and' smoother cup for the heel.

A further object of the invention is to provide a pad having perforations, thereby ventilating, and at the same time lessening the heet to the foot of the wearer.

-A further object of the invention .is to provide an arch supporting plate and an insole which is attached to the 'plate at one end, and disconnected at the other end, whereby a cushioning pad (for reinforcing and supporting the longitudinal and transverse arches) may be sdjustedforwardly or rearwardly, as desired, until the wearer is entirely satisfied with the manner inl which Y the arch is supported.

A further object of the invention is to provide improved fasteners of any convenient shape, to fasten the cushioning pad to the plete. 75

A further object of the invention is to construct the pad from one or :i plurality' of pieces, vulcanized or otherwise put or secured together.

A further object of the invention is to provide a resilient fastener to secure the paid to the plate, and when the pad has been ud. justed to suit the wearer, the pad muy be permanently fastened to the plate by riveting the fastener, which may be accomplished l by an ordinary shoe clerk with a pair of pliers or the like.

Inpructical fields, theidetails of construc-F tion muy necessitate alterations falling within the scope of what is claimed.

The invention comprises' further features and combination of parts, as hereinafter set forth, shown in the drawings, and claimed.
